    A durable and light softshell for big mountain ascents.

    More often than not, mountain adventures come with a side of wind, so be ready with the Arc'teryx Men's Gamma LT Hooded Softshell Jacket. The Gamma LT's Wee Burly Double Weave softshell fabric is made from a lightweight material that offers light insulation against cold temperatures and blocks cold high-winds. The hood is helmet compatible, so you can throw it over your climbing lid without feeling restricted, and the jacket has two large hand pockets where you can warm your fingers before you rope up. The hem is drawcord adjustable, so you can lock in whatever warmth you've accumulated during the approach before you make the final slow and cold push to the summit.

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: M
    • Height: 5'10"
    • Weight: 170lbs

    WHO: I’m 5’10” 170lbs, 31” waist 32” inseam, Athletic build, living in the Southeast of the US with relatively mild winters. I’m kind of a gear-head and have more jackets than I need in my rotation (just ask my wife). I’m normally size M and I got a size M in this one. I’ve had this jacket just over a year now.

    WHAT: In a word, versatile. LT = light weight, add in the underarm gussets and stretchy materials and the shell just moves with you and doesn’t get in the way. It's durable, breathable and has great wind and water resistance (not water proof).

    WHEN: For me this is a 3-season shell, I use it as a stand alone jacket in the spring and fall but may partner it with a midlayer for winter activities. 

    WHERE: I use this thing all over, hiking on the trail or going to the office in the city, this shell just works. And it packs down small enough to take with you wherever you go. We are traveling to NZ south island for a few weeks and this jacket is coming (along with my Beta LT). 

    WHY: It's the best all-a-rounder, I have other jackets that do some things better but I haven't seen one that can do all these things this well.

    STYLE: I love its look and feel. It has sleek simple lines with a perfect athletic cut. Add in this faint lined texture and the outer has an awesome feel. Note: I have a Gamma LT vest that's about 8 years old now and the new texture of the outer is really great. It's one of those things I didn't even know I needed. It's only drawback is the hood makes the collar stand out and look a little funny (I guess that's the price you pay for functionality).

    FUNCTION: I “Needed” a good all-a-round jacket. I love to travel and do outdoor actives, so was looking for something have could handle almost any situation.

    9 out of 10 
    The collar with the hood is its only thing keeping this from being perfect. 
    If you're like me and don't like hoods on anything other than a rain shell then the you'll be happy to know the non-hoody version of this jacket gets a 10 out of 10 in my book. 

    Gamma LT vs Gamma MX
    I have to say I've wanted a MX for over 10 years now. It's a really cool jacket, but the price always kept it just out of reach.
    Quick match up: the MX wins on the cool factor, those extra chest pockets really set it apart from other players in this field and the extra warmth is nice if you're looking to not have to layer (although this was a downside for me living in a warmer climate). Ultimately it was the LT that came from behind and won this match up for me. The LT just fits my life better. The lightweight makes it better for traveling and just a bit more versatile. FYI: I did opt for the Hoody version due to a sale.

    Great fit, bombproof protection.

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: XL
    • Height: 6'2"
    • Weight: 215lbs

    Spent a lot of time selecting a softshell for my specific needs. I wanted something with a high degree of weather / wind protection, uncluttered low-profile design, and no extra insulation. I like to layer a fleece underneath as needed, and prefer to have the option of wearing the shell on its own when it's not so cold. This jacket has served very well in this role. It really feels like a shield from weather and scrapes, and is durable as hell. I wear a Patagonia R2 underneath when it gets cold, and I really don't think it gets much better than this combo. I'm seriously considering buying a second one in another color, it's that good. If you are looking for stand-alone warmth, you may be better served by the Epsilon LT Hoody.

    Great Touring Piece

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    I got this as a lightweight touring softshell. It works beautifully as active layer, breathing well, providing protection from wind, cold, and light precip. It's an anthletic fit so you can layer over it if things get really chilly. In typical arc'teryx fashion, it's simple and minimalist. A few well placed zipper pockets, and that's about it.
    One nice feature is is the stretchy cuffs made from a more slippery fabric. The wrists are a high abrasion area and that fabric allows for better interplay between other fabrics (like on your gloves or mittens). That same fabric is used in the hood, as well, which saves some weight.
    I'm 5'11" and 150 lbs and a medium is a good, well tailored fit.

    Just what I was looking for

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    I wanted a jacket to do three things: wear dayhiking, snowshoeing and for casual wear. I previously had a US Army issue softshell until I learned I could sell it for $250+. That jacket had the best softshell material I’ve ever used and if it had been better sewn and not in Army, foliage green, I would have kept it.

    I replaced it with a Marmot ROM that I had for the past year. It was well built, but boxy and I really didn’t need a jacket that “heavy” with the Gore Windstopper liner.

    In buying the Gamma LT, I was concerned that it would be too tight in the arm holes, which seems to be a concern for me in other jackets. I’m not a big guy, but am fit at 5”09” and 185lbs. The jacket fits great and I can easily layer a base, then a light fleece or sweatshirt. I can even fit a light puffy under it, but that does start to push the limits of the arm holes. I ordered a large, but should have also ordered an XL to try on, then returned the one that didn’t fit as well.

    The sleeves are long, but that’s good and prevents them from riding up if you need to reach for something. As has been mentioned in other reviews, the cuffs are not adjustable but seem to be set for where I would if they had Velcro. As a personal preference, I would still like to be able to adjust my own cuffs as sometime you just need to tighten them down and other times you might want to increase the airflow.

    The body of the jacket is lean which is nice if you’re wearing a pack or moving through brush. I would prefer to have a little more room so that anything I wear on my belt, including a phone or knife, would not so easily print through the jacket when it’s zipped up. The back of the jacket is nicely longer than the front, but again I would prefer just another inch of length in front, so that my fleece that’s hanging out isn’t getting wet.

    The hood as also previously reviewed is very large, but can be cinched down to fit well without a helmet.

    The material itself is both very tough yet comfortable and stretches well. I’ve had the chance to wear the jacket from below freezing in the 20’s up into the mid’50’s. The jacket sheds light rain very well, but does start to wet out after 30 or so minutes. I’ve remained dry underneath, but you just have to remember the limits of the material. I do very much like how breathable it is though. Just to be clear, there is no lining, backing material or insulation on the interior.

    Overall, an excellent piece of gear that should serve me well in a variety of roles. I got the gray, which surprisingly came with some nice, blue trim along the zippers and collar. When they make a version all in the same blue, I’ll buy one of those too.

    Most versatile softshell on the market

    • Familiarity: I've used it several times
    • Fit: True to size

    The Arc'teryx Gamma LT Hoody is one of the most versatile softshells on the market by perfecting what is required for a softshell. The Gamma LT Hoody was meant for the alpine and has all the features you need and nothing you don't. "A designer knows he has achieved perfection not when there is nothing left to add, but when there is nothing left to take away." - Antoine de Saint-Exupery. The Gamma LT Hoody will be my main layering piece on any volcano climbs in the PNW during the summer.I'm 5'10" and roughly 165lbs with 33" waist and the Gamma LT Hoody is sized to accommodate a midlayer comfortably like a Atom LT hoody or a mid-weight down sweater.


    Fantastic fit with options for layering underneath

    Highly wind resistant but breathes incredibly

    Great water-resistance and dries quickly

    Hood accommodates over sized helmets

    Velcro-less cuff makes layering easy


    A little pricey

    Most versatile softshell on the market

    Definitely not a LT jacket

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    This is one burly shell. Yes Burly double weave lives up to its name. Its also quite heavy (over 600gms for my medium). It is quite windproof for just a stretch woven fabric with no membrane. It breathes decent enough but has no real insulating value to the fabric. Good 4 way stretch, with a slightly trim cut (a tad slimmer than my gamma MX), 2 good sized hand pockets and 1 internal pocket. nice overall fit with clean lines. The inner fabric is not the softest against the skin (when wearing t shirts etc), and as mentioned has no fleece backer and thus minimal insulation.

    Overall good performing soft-shell, cuts wind and covers you in light precip


    • Familiarity: I returned this product before using it
    • Fit: Runs small

    I ordered this jacket about a week ago and when I received it, I was sad to find that the jacket was too small. Even with the athletic cut and sizing up for the difference it was still too small. Normally wear an XL in everything no matter what it is. But going to need to buy an XXL this time.

    Excellent Softshell

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    I purchased the Gamma LT Hoody in late winter after previously owning the Patagonia Guide Hoody. I really liked the Guide Hoody initially, but there were several design elements I didn't care for. For instance, I wear size medium and found the sleeves to be excessively long. While this normally wouldn't be an issue, the Guide Hoody didn't have any method of managing the sleeve length via velcro straps or some type of cinch system. That issue, coupled with the lack of breathability due to the interior fleece lining led me to look elsewhere for a solid softshell. I'm pleased to say my search began and ended with the Gamma. This shell is spectacular in each area the Guide Hoody lacked. First, Arc'teryx conveniently addressed the previously noted sleeve issue by crafting the base of the sleeve using an elastic fabric that keeps the sleeves in place without the hassle of velcro straps. They used the same excellent design element on both my Atom LT Jacket and Atom SV Hoody to great affect. The exterior fabric of the Gamma is made using the Arc'teryx Burly Weave, and it feels bomber. I have full confidence I can rub the jacket against any surface without causing any wear to the fabric. It feels super durable, but is also soft to the touch. Given the durability, when I first received the jacket I thought it wouldn't be that breathable, and I was completely wrong. The Gamma breathes better than any other layer I own and it is now my three season go-to piece for most outdoor pursuits.

    Winter: all the time, everywhere

    • Familiarity: I've put it through the wringer
    • Fit: Runs large

    For winter, I spend most of my time wearing this jacket. It's the most versatile jacket I've ever owned.

    The fit: I am 6'2", 170lbs and surprisingly bought a small. I can fit an UL down jacket/expedition baselayer underneath. Sleeve length and overall length is great. Size up for more layering options.

    Things I've used this jacket for:

    Bike commuting in town, snow cave building, snowshoeing, glisadding, shooting, lots of hiking.

    Conditions I've used this jacket in: extreme wind, sub zero temps (with a puffy underneath), immersed in powder, wet and dry snow, heavy rain.


    - Huge helmet compatible hood. In high wind, it blows off your head if it's not sinched down. The front of the hood extends far over your head, almost like a hat (which is good during active snowfall). The hood has two draw cords on the side to make it tighter and a rear draw cord to make it tighter-er (?). The bill of the hood is semi-stiff.

    - Two huge hand pockets. Mesh lined, easily fit a pair of gloves and a hat in one pocket. There is also an internal chest pocket which fits a phone (no headphone port).

    -Two draw cords at the bottom which can be operated with one hand.

    -Wind guard behind the main zipper. The hand pockets have a much tighter zipper to keep wind out, but no wind guard. The main zipper has large teeth, is very easy to move, and has a large pull tab.

    -Slight drop-tail in the back of about 1-2 inches.

    -Cuffs have elastic panel (no velcro)

    If I am working vigorously, I won't wear this jacket in temperatures over 30 degrees unless it's windy. Standing still, I am find down to mid 30's with it and just a T-Shirt. Breathability is good compared to any hardshell, but it's a windproof softshell which is limiting.

    The outer face sheds snow well. The first places to get wet seem to be behind the neck and upper shoulders for some reason. It stays drier than a windshirt or DWR treated puffy. It does okay in the rain but don't expect it to serve as a rainshell.

    Winter: all the time, everywhere

    Great product

    • Familiarity: I've used it several times
    • Fit: True to size

    I've been looking for a softshell for a while and finally found it. This jacket is relatively wind resistant, but still very breathable. I've taken it bc and Nordic skiing so far and the breathability has been great. The fabric is fantastic. Tons of stretch making it very comfortable and non restrictive. And the fabric feels super durable.

    Great for what it is

    • Familiarity: I've used it several times
    • Fit: True to size

    This jacket is great for what it is. A lighter weight, stretch woven, minimally featured softshell. It's great for active pursuits in cold weather. I've had it out backpacking and hiking and it's just what I wanted. The fabric appears very durable, but it results in a weight penalty for sure. I'd say it's highly wind resistant, but definitely not windproof. The upside is that it is very breathable if you're working hard. The elastic cuffs and hem draw cord keep the wind out. The hood is the typical head swallowing "helmet compatible" type but the adjustments work well to tailor the fit. My one complaint is that the hood drawstrings sit inside the jacket, so to adjust you have to unzip; more of a personal inconvenience than a real flaw. The two hand pockets are mesh lined and extend from below the armpits to the waist and can double as vents. The pockets are completely accessible with a pack on.

    I'm 6' broad shoulders and the large fits perfect. It is a true athletic cut and I could get a baselayer and maybe another light layer under it. Puffy is a no go for me in the arms.

    In the end, I don't think I'd pay full price. Wait for a coupon or sale on this one; still a good piece, just not full price great.

    Great for what it is

    Great breathable shell and TOUGH

      I bought this for a do everything type of softshell including wearing casually in the winter. When I bought it I had to go up a size because it's a very athletic cut. I usually am a Medium in pretty much everything and for this I had to go with a large. The double weave material is extremely durable, which Backpacker magazine just gave it an award for. Unfortunately I decided to return it because it didn't offer any insulating qualities and as for a shell, I already have a Beta AR. I ended up going for the Gamma MX which I'm very happy with. They both do a decent job of cutting wind (not windproof) but I find that the insulation of the Gamma allows for more versatility.

      Great simple, clean jacket

      • Familiarity: I've used it several times

      This jacket is exactly what I was after. It's simple, has clean lines, and fits great over my Atom SV. Zippers have smooth action, which is good when using gloves. No external chest pockets, and I haven't tried this jacket with a pack on, so it's hard to say if stuff will be accessible. Material feels pretty sturdy. I wear a large, and I think it fits true to size.

      I have been using the GammaLT over the AtomSV hoody for the coldest days this winter - bloody brilliant combo! For less extreme cold temps, the Lorum under the GammaLT makes for the most comfortable, cozy jacket i have ever worn...

      How does Gamma LT compare to the new Psiphon FL? Which is warmer/windproof?

      Sean, the Gamma LT Hoody will offer more warmth and wind resistance. The Psiphon FL Hoody is really designed and built for rock and alpine climbing. The Siphon FL Hoody has a trimmer fit and will offer more abrasion resistance and will dry more quickly. Hope that helps!
